Abstract

The present invention relates to a tripod with an improved structure that allows the height of the lifting opening, on which an article or fixed attachment is mounted, to be easily adjusted by raising and lowering the lifting opening in the up and down directions, and also allows the tripod legs, which are rotatable to be folded in three directions by using a locking mechanism, to be easily locked and fixed to the lifting fixing side of the connecting socket coupled to the lower part of the lifting fixing stand, and allows the unlocking operation of the locking mechanism to be easily operated. Furthermore, the present invention relates to a tripod with an improved structure that allows the angle to be varied stepwise when locking the tripod legs, and enables the locking mechanism to be easily released in a one-touch manner when unlocking the tripod legs. The present invention, for achieving the above objective, is characterized by a technical configuration comprising: a lifting fixing member that moves a lifting member, on which an article or a fixed attachment is mounted, in a vertical direction; a coupling socket coupled to the lower part of the lifting fixing member, having a connecting member provided in three directions on the outer edge portion, and a plurality of locking sections formed on the outer edge of the connecting member to adjust the locking angle of the tripod leg; a connecting socket each pivotably hinge-coupled to the connecting member and equipped with a locking mechanism that fixes the angle of the tripod leg relative to the connecting member through adjustment of the rotational angle of the tripod leg and locking coupling; and a tripod leg each coupled to the end of the connecting socket and pivotably connected to the connecting member.

Claims (4)

  1. A lifting fixing member (100) that lifts and lowers a lifting opening (120) on which an item or fixed attachment is mounted in the upper direction, a connecting socket (150) that is coupled to the lower part of the lifting fixing member (100) and has connecting members (160) provided in three directions on the outer edge portion and a plurality of locking sections formed on the outer edge of the connecting members (160) to adjust the locking angle of the tripod leg (200), and a connecting socket (310) that is hinge-coupled to each of the connecting members (160) so as to be rotatable and has a locking mechanism (300) that fixes the angle of the tripod leg (200) relative to the connecting members (160) by adjusting the rotation angle of the tripod leg (200) and locking coupling; In a tripod having a tripod leg (200) that is rotatably connected to a connecting socket (310) at each end and connected to a connecting member (160), and having a locking member (350) that is selectively locked and connected to or unlocked from one of the first, second, and third locking members (161, 162, 163), a connecting bolt (360) is formed through an elongated hole (352) through which the connecting bolt (360) passes so as to be mounted to the connecting socket (310) by the connecting bolt (360). The tripod is characterized by having a locking release projection (190) protruding outwardly from the outer circumference at a position spaced apart from the first, second, and third locking sections (161, 162, 163), so that when the connecting socket (310) rotates, the locking member (350) interferes with the locking part of the locking member (350) and releases the locking coupling state between the locking member (350) and the connecting member (160).

Description

Tripod The present invention relates to a tripod, and more specifically, to a tripod with an improved structure that allows the height of a lifting opening, on which an article or fixed attachment is mounted, to be easily adjusted in the up and down directions, and also allows a tripod leg that can rotate in three directions with respect to a coupling socket coupled to the lower part of the lifting fixing member to be easily locked or unlocked with respect to the coupling socket using a one-touch locking mechanism. When camping outdoors, since there is no support to fix the lantern in place, the method mainly used was to install it on the ground using a tree as a support and hang the lantern. There is a problem in that it is inconvenient to use because the lantern shakes when the wind blows, as you cannot find wood outdoors, such as at a campsite, or you have to tie or hang the lantern by driving the lower part of the tree used as a support deep into the ground. In addition, since the tree or pole from which the lantern is suspended is a fixed object, it was impossible to adjust the height or direction of the lantern light, which caused inconvenience in use. Conventional technologies related to supports for existing lanterns include technologies disclosed in Korean Utility Model Publication No. 20-2001-0000751 and Korean Registered Patent No. 10-1014832. Meanwhile, the tripod-shaped support is used not only for the lantern described above but also as a support for items such as surveying equipment. As for prior art related to tripods for surveying equipment, as disclosed in Korean Registered Patent Publication No. 10-1659744 "Anti-slip tripod for surveying equipment" (Registration date: September 20, 2016), the spikes on the tripod legs that fix surveying equipment on irregular terrain such as soil, sand, or gravel are improved so that the surveying equipment can be fixed stably without shaking even on smooth and regular terrain such as marble or asphalt, and an anti-slip member is provided on the tripod legs. As disclosed in Korean Published Patent Application No. 10-2024-0033874, "Automatic height adjustment and leveling device for a tripod" (Date of publication: March 13, 2024), a servo motor is installed on the fixed plate flange of the tripod to enable the lifting and lowering of a guide bar for lifting and lowering located at the bottom of the top plate inserted into the fixed plate flange, and a support bar for leveling and lowering is installed at the bottom of each of the three fixed leg parts connected by hinges and equipped with a servo motor. Information is collected using a gyro sensor and an ultrasonic sensor, and a remote control switch transmits this information to a control unit via a wireless communication module. The control unit then operates each servo motor to level the top plate of the tripod and automatically raise it to the height required by the user. By installing both a leveling and height adjustment device on the tripod, the leveling and height of the top plate are synchronized, thereby facilitating the operation, use, and storage of the tripod. However, existing tripods that function as supports for items such as lanterns, surveying equipment, cameras, camping tables, shelves, and clothes hangers consist of a body that supports the item and angle-adjustable tripod legs at the bottom of the body. To facilitate portability during transport or storage, it is necessary to fold and rotate the legs so that they are flush against the body to minimize volume. This has the disadvantage of requiring a separate locking mechanism to lock the tripod legs in order to maintain the folded and rotated state. In addition, even if existing tripods are equipped with a locking mechanism for locking or unlocking the tripod legs, they have the disadvantage of reduced usability due to a complex structure that prevents the user from operating the locking mechanism with one hand.
